ABSTRACT:
A magnetic resonance imaging system is provided, which can provide the homogeneous magnetic field to obtain a head anatomic image with a high resolution and high SNR by coaxially disposing a receive-only phased array antenna inside a transmit-only antenna with a predetermined gap, and thereby a detailed and accurate image of a man's head can be obtained. In the present invention, the system comprises: a transmit-only antenna comprising at least two saddle quadrature antennas connected with each other to form a ring shape, one of the connections being a joint and the remaining connections being formed in an overlapping fashion; and a receive-only phased array antenna comprising a plurality of receive-only antennas connected with each other to form a ring shape, one of the connections being a joint and the remaining connections being formed in an overlapping fashion, wherein an inner diameter of the receive-only phased array antenna is shorter than that of the transmit-only antenna, and the receive-only phased array antenna is coaxially disposed inside the transmit-only antenna with a predetermined gap.
